Hi, I have 89 cherokee with 201k and I will be swapping the motor with a 91 H.O. 120k while keeping the Renix system, I would also like to swap the transmission along with the transfercase from the 91. Ive read the write-ups for engine swap but I haven't found anything on using the newer transmission. Can anybody tell me what I'll need to do in order to use the newer transmission? Any help would be greatly appreciated.
